Answer:

see explanation

Step-by-step explanation:

Calculate C by adding corresponding components of A + B

C = \left[\begin{array}{ccc}4\\-7.5\\\end{array}\right] + \left[\begin{array}{ccc}-2.5\\5\\\end{array}\right]

= \left[\begin{array}{ccc}4-2.5\\-7.5+5\\\end{array}\right]

= \left[\begin{array}{ccc}1.5\\-2.5\\\end{array}\right]

ololo11 [35]

Answer:

From the graph attached, we know that \angle 1 \cong \angle 5 by the corresponding angle theorem, this theorem is about all angles that derive form the intersection of one transversal line with a pair of parallels. Specifically, corresponding angles are those which are placed at the same side of the transversal, one interior to parallels, one exterior to parallels, like \angle 1 and \angle 5.

We also know that, by definition of linear pair postulate, \angle 3 and \angle 1 are linear pair. Linear pair postulate is a math concept that defines two angles that are adjacent and for a straight angle, which is equal to 180°.

They are supplementary by the definition of supplementary angles. This definition states that angles which sum 180° are supplementary, and we found that \angle 3 and \angle 1 together are 180°, because they are on a straight angle. That is, m \angle 3 + m \angle 1 = 180\°

If we substitute \angle 5 for \angle 1, we have m \angle 3 + m \angle 5 = 180\°, which means that \angle 3 and \angle 5 are also supplementary by definition.
